mid 11's but sometimes richer which is why im thinkin it might be spark blow out or something.. i watched some videos and it sure seems like thats whats happening..

im runnin ngk bkr7e's gapped to .31 and they are about a year old, i've got some brand new ones i was going to try gapping to .27 and see what happens, if that helps but not all the way i'll try .25. we'll see how it goes, im betting its something silly cause i didnt rush or skip any steps.. tried to go the extra mile on everything i could..

it might just be in the tune tho, i sent john a log and a copy of my tune so maybe he can spot something.

idk.. hope i get it figured out soon tho..

virtual dyno is still showing power bein made in the 300s, an i lowered the boost haha


That could be tip-in related...

Sounds like a good plan, interesting it's only doing it in a specific spot on the map at a higher PSI.

If you're running copper plugs that are a year old... yeah its time for a change. Car sounds great man good work.

Do you have them indexed like Vadim recommends? I've heard having them properly indexed helps w/ spark blow out.

Funny how something as simple as changing a manifold will ruin a tune!:tickled_pink:

Aren't you swapping over to speed density or something as well though?
